How to calculate the weight

weight of any tube can be calculated with the following formulas


Imperial Example
density (lbs/in³) 0.284 lbs/in³
x
(OD² - (OD - 2xT)²) (3.0 in² - (3.0 in - 2x0.022 in)²)
x
Length 12in

π/4
=
weight 0.702  lbs


Metric Example
density (g/cm³) 7.85g/cm³
x
(OD² - (OD - 2xT)²) (50.0 mm² - (50.0 mm - 2x1.0 mm)²)
x

=
weight 1.209 kg
